This is my first pair of prescription goggles and I'm very impressed with them.I've heard horror stories about buying prescription goggles online, so I was quite nervous to open the package when it came.The prescription lenses came installed in the goggles, with a pair of regular lenses in the box. The goggles are well sealed and come with a comfortable, easy to adjust strap.These goggles were also the cheapest ones I could find that came with prescription lenses, they were less than $100 which is significantly less than I was expecting to pay (the local dive shop was selling prescription goggles for around $300).
